Walmart: buy or wait and see?

$WMT (-2,1%) Walmart is a real heavyweight in the retail sector and is present everywhere in the USA. The stock is considered to be stable and perfect for those who prefer safety to big risks. At least that's what I've read. I find it particularly exciting that Walmart is really stepping on the gas when it comes to e-commerce and looks better than most others in the States. They are also positioning themselves more strongly in terms of sustainability. Of course, competition like Amazon never sleeps, but Walmart is still very interesting. There are also regular dividends. They may not be spectacular, but they are solid. What do you think? Is it worth getting in now, or has the train already left the station?
